Fracture of the zygomatic bone is a common fracture of the facial skeleton; the zygomatic bone forms the most anterolateral projection one on each side of the middle face. The zygomatic bone is attached to the maxilla at the zygomaticomaxillary (ZM) suture and alveolus forming the zygomaticomaxillary buttress.

Zygomaticomaxillary Complex (ZMC) fractures result from blunt trauma to the periorbital area (viz. malar eminence). ZMC fractures are also referred to as tripod, trimalar, tetrapod, quadripod, or malar fractures.
In anatomy, the zygomatic arch, or cheek bone, is a part of the skull formed by the zygomatic process of the temporal bone (a bone extending forward from the side of the skull, over the opening of the ear) and the temporal process of the zygomatic bone (the side of the cheekbone), the two being united by an oblique ...
zygomatic arch, bridge of bone extending from the temporal bone at the side of the head around to the maxilla (upper jawbone) in front and including the zygomatic (cheek) bone as a major portion.
Definition. The zygomatic bone articulates with the sphenoid bone, maxilla, frontal bone, and temporal bone to form the lateral wall of the floor of the orbit, part of the temporal and infratemporal fossa, and the prominence of the cheek.
tri·pod frac·ture. a facial fracture involving the three supports of the malar prominence, the arch of the zygomatic bone, the zygomatic process of the frontal bone, and the zygomatic process of the maxillary bone.
These complexes are referred to as the zygomaticomaxillary complex. The upper and transverse maxillary bone has the zygomaticomaxillary and zygomaticotemporal sutures, while the lateral and vertical maxillary bone has the zygomaticomaxillary and frontozygomatic sutures.
The most common cause of zygomatic fractures is violent altercation. This is then followed by motor vehicle accident (MVA). These fractures can also occur during falls or activities such as cycling or skiing.
Fractures of the ZMC or zygomatic arch can often lead to unsightly malar depression, which should be corrected to restore a normal facial contour. ZMC fractures can also cause significant functional issues, including trismus, enophthalmos and/or diplopia, and paresthesias of the infraorbital nerve.
After the nasal bones, the mandible is the most common site of facial fractures; mandibular fractures often require open reduction.
